No default value for sample.vfn in TrainImagesClassifier
There is no default value for the sample.vfn parameter in otbcli_TrainImagesClassifier.
-sample.vfn <string> Field containing the class integer label for supervision (mandatory, default value is )
I did try to look where it came from, but I lost myself in all the classes. Maybe its best if the author could take a look.
(Ok I admit this is an excuse to test the issue feature of github
Steps to reproduce
